Sorry about not posting more often...
I have been spending every other week on this project and I haven't really had too much to show other than research until this week.
I definitely don't have enough to push anything useful, but I finally have a solid idea of how this is going to work. I also now have a working knowledge of all of the skills that will be necessary to complete this project.  Over this summer I have learned to use PHP, HTML5, CSS, JavaScript, SQL, and AJAX in order to meet these goals.  I currently am at a point where I have some very basic artwork and the ability to draw a board from the stored game data and basic login functionality.  I hope to have a working game by the end of the summer.
